HERMES: A new stand-alone platform for active noise control and damage detection

In this paper, a new stand-alone board explicitly designed to active noise and vibration control and for damage detection, is presented. The system is based on ADSP-21060 SHARK and for flexibility the hardware is divided in two parts: the main processor board, containing the A/D and D/A converters, able to work as stand-alone or in a multiprocessor system being configurable without any hardware change; the I/O interface boards. All the boards are accommodated in a compact rack. The authors have developed all the software tools needed for application in the active noise control or damage detection framework. The software parameters may be changed by the user via a user friendly interface from a host PC connected to the system via a RS232 port. The system has been extensively testes in different applications with encouraging results, work in progress are related to the use of the platform to implement M.I.M.O. ANC systems.
